Please let us know what you find. I may appear to want to dismiss any news but that is not the case. I just want to be sure that when or if they actually do something different it will work and not just be the same old thing rehashed yet again.

Just thought I'd share - my MY14 BRZ had crickets. I took it to the dealership 3 days after I bought it, they replaced it with the updated unit and no more crickets with Costco 93 and Mobil 93 octanes. Just recently made the switch to E85 at a Mobil and the crickets were back immediately at start up. By the time I got home they were quiet again.
TL;DR - new/redesigned pump seems to have fixed crickets for me at least. |

I can make mine come and go at will by using certain fuels at specific times of year.

Had the "new" fuel pump installed today at Toyota.
No more chirp. I'm currently on Costco 91, which had the chirp before this new one. Hopefully it's fixed, but I'ma give it a month or so before saying it's fixed. 2016 FRS |

Let us know. Almost every person to get their pumps changed started out with "New pump no chirps" but the vast majority were back within a week.

Remember, you have to get the engine and pump HOT and you have to be running low lubricity fuel, like gasoline with 10% ethanol sold at most pumps in the US. Then you'll know if its chirping or not. |

Embrace the crickets. If it ain't broke, don't fix it.

Draw a wide line from Alaska to South Florida, via New York. I've fueled in all those US states, and Canadian provinces, and never heard a single cricket.
With forced induction, etc... for almost 30,000 miles. I've always thought the "bad fuel" or "poor lubricity" argument was, at best, a lip-service band-aid for very poor manufacturing tolerances, and very poor material quality control. Automotive gasoline has very low lubricity, and the variation between fuels is inconsequential. Similar issues are evident all over the engine and car, from axle nuts to sealing surfaces. Why should the DI fuel pump be any exception?

http://papers.sae.org/2013-01-0253/ http://papers.sae.org/2011-01-0930/ I haven't heard crickets in 3 years and 40,000 miles, 99% of my driving is within a small region. I think that for a powertrain designed for a <$25k price point suffers from looser QC and as such the pump is designed to 'wear in', I'm not the only one who's had their pump go quiet after 'breaking in' and a few got lucky having one in spec off the shelf. |
